Replace damaged or broken wheel studs on the front or rear axle hub assembly by pressing out old studs and installing new ones.

Warnings

⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight.
Ensure parking brake is set and front wheels are chocked if working on rear axle, or rear wheels chocked if working on front.

Tools required

Parts

  • Wheel stud × 1 — Use OEM specification

Preparation

  1. Park vehicle on level surface and engage parking brake
  2. Chock wheels opposite of the corner being serviced
  3. Loosen wheel lug nuts 1/4 turn before raising vehicle
  4. Raise vehicle with floor jack and support securely on jack stands at frame rails
  5. Remove wheel completely

Procedure

  1. 1
    Remove brake caliper and rotor
    Remove brake caliper mounting bolts and hang caliper with wire or bungee cord to avoid stressing brake hose. Do not let caliper hang by brake line. Remove brake rotor by pulling straight off hub. If rotor is stuck, use rotor screws if equipped or tap with rubber mallet.
  2. 2
    Identify damaged stud location
    Locate the broken or damaged wheel stud on the hub assembly. Mark its position if needed for reference. Inspect hub face for damage or distortion around stud hole.
  3. 3
    Remove damaged wheel stud
    Using a ball joint press or hydraulic press, press the damaged stud out from the back of the hub assembly. If a press is not available, use a hammer to drive the stud out by striking it from the front face. The stud will push out through the rear of the hub. Ensure no damage occurs to the hub face or surrounding studs during removal.
  4. 4
    Clean stud bore
    Use wire brush to clean the stud bore hole in the hub assembly, removing any rust, debris, or metal shavings. Ensure the hole is clean and free of obstructions. Inspect for cracks or damage to the hub around the stud hole.
  5. 5
    Install new wheel stud
    Insert new wheel stud into hub from the rear side. The serrated portion of the stud should be facing toward the front of the hub. Stud should slide through easily but will not pull through without force. Apply light coat of anti-seize to serrations if desired, though not required.
  6. 6
    Seat wheel stud
    Use ball joint press or stack washers and a lug nut to pull the stud into position. If using washers and lug nut method: place 3-4 flat washers over stud, thread lug nut on, and tighten lug nut to draw stud into hub. Continue tightening until stud shoulder seats firmly against rear of hub. Remove lug nut and washers. Verify stud is fully seated and flush with other studs.
    Do not overtighten lug nut during seating process as this can damage stud threads. Stop when stud shoulder contacts hub.
  7. 7
    Reinstall brake rotor
    Clean hub face and rotor mounting surface with wire brush. Install brake rotor onto hub, aligning any indexing holes if equipped. If rotor screws are used, install and tighten to secure rotor during caliper installation.
    Torque spec
    Cover Screws12 Nm (9 lb-ft)
  8. 8
    Reinstall brake caliper
    Position brake caliper over rotor and align with caliper bracket. Install caliper mounting bolts and tighten to specification. Ensure brake pads are properly positioned on both sides of rotor.
    Torque spec
    Mounting Bolts31 Nm (23 lb-ft)
  9. 9
    Install wheel and torque lug nuts
    Install wheel onto hub, aligning holes with all studs including the newly installed one. Thread all lug nuts by hand to ensure proper thread engagement. Tighten lug nuts in a star pattern to proper torque specification in two stages: first to 50% torque, then to full specification.
    ℹ️Verify new stud accepts lug nut without cross-threading before final torque.
    Torque spec
    Wheel Lug Nuts156 Nm (115 lb-ft)

Reassembly

  1. Lower vehicle from jack stands carefully
  2. With vehicle on ground, re-torque wheel lug nuts to specification in star pattern to ensure proper seating
  3. Test drive vehicle and listen for any unusual noises from wheel area
  4. Re-check lug nut torque after 50-100 miles of driving

Verification

  • Verify new wheel stud is fully seated and flush with other studs on hub
  • Confirm lug nut threads smoothly onto new stud with no binding or cross-threading
  • Check that wheel is secure with all lug nuts properly torqued
  • Test brake pedal feel and ensure brakes operate normally
  • Verify no vibration or noise during test drive
